The lower end of described lower Triangular Arm is articulated with on Self-discharging vehicle sub car-frame.
The upper end thereof of described upper Triangular Arm is on dump truck carriage floor.
Described inhibiting device is fixed on Self-discharging vehicle sub car-frame.
Described inhibiting device is shaped steel or bending part, can bear the application force being not less than hydraulic actuating cylinder 1.5 times of thrusts.
Described hydraulic actuating cylinder is single-action piston cylinder.
Described upper Triangular Arm, lower Triangular Arm, telescopic lever, fixed length pull bar are Casting Parts.
When self-discharging carriage lifting, hydraulic actuating cylinder extends, and forms thrust to upper Triangular Arm, by the transmission of power, and carriage lifting, upper Triangular Arm and lower Triangular Arm generation relative displacement, telescopic lever extends; When telescopic lever is stretched to maxim, telescopic lever, upper Triangular Arm, fixed length pull bar three relative position no longer change, and when hydraulic actuating cylinder continues to extend, lower Triangular Arm starts to rotate, and compartment continues lifting, until hydraulic actuating cylinder is elongated to maxim.When compartment lands, hydraulic actuating cylinder bounces back, and each parts are by above-mentioned reversing sense motion, and initial condition is got back in compartment.
The utility model, in self-discharging carriage lifting process, is first rotated by upper Triangular Arm and realizes a lifting amplification effect, is then rotated by lower Triangular Arm and realizes secondary lifting amplification effect, can realize twice lifting amplification effect.Amplify because twice lifting can be realized, so under the prerequisite that can realize demand lifting angle, suitably can reduce the size value of upper and lower Triangular Arm, to reduce dumping car center-of-gravity position; Telescopic lever can prevent hydraulic actuating cylinder and upper Triangular Arm from motion process, occurring movement dead.
The beneficial effects of the utility model are: this mechanism can realize twice lifting and amplify, and use the load lifting cylinder of more short travel to obtain wide-angle lifting, and it are less to take up room, and can reduce dumping car center of gravity, improves its riding stability and lifting stability.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Figure 1-Figure 2, tipper lifting mechanism, comprise two shrinking connecting-rod devices and hydraulic actuating cylinder 2 and crossbeam 6, shrinking connecting-rod device comprises Triangular Arm 1, telescopic lever 3, fixed length pull bar 4, lower Triangular Arm 5.Wherein go up Triangular Arm 1 and be articulated with cabin floor 7, upper Triangular Arm 1 is hinged with telescopic lever 3, and upper Triangular Arm 1 is hinged with fixed length pull bar 4; Lower Triangular Arm 5 is articulated with subframe 8, and lower Triangular Arm 5 is hinged with telescopic lever 3, and lower Triangular Arm 5 is hinged with fixed length pull bar 4; The equal stationary links in middle part of upper Triangular Arm 1 and lower Triangular Arm 5, two shrinking connecting-rod devices are connected by connecting rod, are hinged with hydraulic actuating cylinder 2 between two connecting rods; Crossbeam 6 is fixed on subframe 8, is positioned at lower Triangular Arm 5 front lower portion, the application force can implementing upwards to lower Triangular Arm 5, and the lower Triangular Arm 5 of restriction rotates; Simultaneously in lifting mechanism first time lifting amplification process, crossbeam 6 is played a supporting role to whole mechanism, and therefore crossbeam 6 must be fixed, can bear the application force being not less than hydraulic actuating cylinder 1.5 times of thrusts.Hydraulic actuating cylinder 2 is single-action piston cylinder, and upper Triangular Arm 1, lower Triangular Arm 5, telescopic lever 3, fixed length pull bar 4 are Casting Parts.
Tipper lifting mechanism is arranged in dumper frame, and wherein hydraulic actuating cylinder 2 is positioned at line of centers, symmetrical each one of shrinking connecting-rod device line centered by hydraulic actuating cylinder 2.
As shown in Figure 3, when self-discharging carriage lifting, hydraulic actuating cylinder 2 extends, and forms thrust to upper Triangular Arm 1, by the transmission of power, this thrust on cabin floor 7, carriage lifting, this at present Triangular Arm 5 do not move; Relative displacement is there is in upper Triangular Arm 1 with lower Triangular Arm 5, telescopic lever 3 extends, along with hydraulic actuating cylinder 2 extends, when telescopic lever 3 is stretched to maxim, lifting mechanism has rotated first time lifting amplification effect by upper Triangular Arm 1, and now telescopic lever 3, upper Triangular Arm 1, fixed length pull bar 4 three relative position no longer change.
As shown in Figure 4, when hydraulic actuating cylinder 2 continues to extend, telescopic lever 3, upper Triangular Arm 1, fixed length pull bar 4 three relative position no longer change, this at present Triangular Arm 5 stressed start rotate, compartment continues lifting, until hydraulic actuating cylinder 2 is elongated to maxim, lifting mechanism has rotated second time lifting amplification effect by lower Triangular Arm 5, and now carriage lifting is to maximum angle.
When compartment lands, hydraulic actuating cylinder 2 bounces back, and each parts are by above-mentioned reversing sense motion, and initial condition is got back in compartment.
In self-discharging carriage lifting process, amplify because twice lifting can be realized, so under the prerequisite realizing demand lifting angle, suitably can reduce the size value of upper Triangular Arm 1 and lower Triangular Arm 5, to reduce dumping car center-of-gravity position.Telescopic lever 3 length is scalable, and telescopic lever 3 maxim must ensure that hydraulic actuating cylinder 2 and upper Triangular Arm 1 there will not be movement dead in motion process.
